Technology Description:

Inlyte Energy will engineer robust cyclability of the sodium metal halide (NaMx) battery’s iron chemistry for next-generation grid storage. The NaMx iron chemistry’s raw storage materials are table salt and iron, two of Earth’s most abundant and low-cost materials. The NaMx battery displays excellent safety, high efficiency, and a long life. Limited research on the sodium/iron chloride battery chemistry has shown variable cycling performance, the number of charge/discharge cycles it can complete before losing performance. Inlyte Energy will perform a systematic study, using a sodium/iron chloride cell, using electrochemical measurements and materials characterization to isolate the factors that allow for long cyclability and engage in a parallel effort in scaling NaMx battery manufacturing for the grid.
